ISAAC MAGUIRE, OF 'ALBANY, NEl/V YORK, ASSIGNOR OF ONE-HALF OF HIS RIGHTTO JOHN MAGUIRE, OF SAME PLACE.

HINGE FOR STOVE-DOORS.

SPECIFICATION forming part of Letters Patent No. 231,184, dated August17, 1880.

Application filed November 20, 1879.

To all whom it may concern Be it known that I, ISAAC MAGUIRE, of thecity and county of Albany, and State of New York, have invented certainnew and useful Improvements in Hinges for Stove-Doors, of

which the following is a full and exact description.

The object of my invention is to provide a cheap and reliable mode ofbin gin gstove-doors,

so as to dispense with the present expensive mode of doing it. As atpresent generally practiced, the ears for forming the hinges on the doorand door-frame are drilled for the hinge-pin, while the door is held toits place on the door-frame. This, from the difficulty of drilling twosets precisely alike, involves the necessity of placing thetwo partsthat are drilled together in precisely the same relation in the stove,and if a hinge is broken on either the door or frame after the stove ismounted it is necessary to take the stove apart to drill the hinge whilethe door and frame are together, so as to produce an exact coincidenceof. the hinge-pin holes.

5 To remedy the defects above referred to my invention consists of theconstruction herein shown and described, whereby the parts eonstitutin gthe hinge are entirely concealed from 7 view when the door is closed,and are cast so 0 that they fit together without being drilled, and sothat all the parts that are cast from the same patterns will beperfectly interchangeable, and the door, which is horizontal, iseffectually guarded against displacement with- 3 5 out the use of apintle or any other separate attaching device.

In the accompanying drawings, which form a part of this specification,and to which reference is herein made, Figure l is a front elevation ofa door and door-frame of a stove Fig. 2, a horizontal section at theline a: 00 of the hinge end of same, showing the position of the partsof the hinge when the door. is closed; Fig. 3, the same with the dooropen; Fig. 4, 5 a front elevation of the hinge end of the doorframe, andFig. 5 a front elevation of the hinge end of the door.

As shown in the drawings, A is the door frame of a stove, which may bemade of any desired form and size. Said frame is provided at its hingeend with one or more openings, (0, for receiving the hooks formed on thedoor, as hereinafter described.

B is the stove-door, provided with 011% more curved hooks, b, whichenter the openv ings a, as shown in Figs. 2 and 3, in such manner thatphe concave parts of said hooks will engage with the convex swells onthe back of the door-frame close to the rear side of the openings at.

D are guards or lugs for guiding the hooks I). Said guards are cast uponthe door-frame, beside each opening a, at the opposite side of theopening from the swell C. These guards extend partially over the convexparts of the hooks I), so as to govern the movement of said hooks andretain the door B in place during its opening and closing movement-s.

E is a stop formed on the top edge of the uppermost hook, I), for thepurpose of preventing the door from swinging far enough to carry thehooks out of the'openings. On small doors, where only one wide hook willbe needed, the stop E will be placed on the top edge of it, in theposition shown in the drawings.

The door is hung in its place by slightly raising the outer end of it,so that the upper hook, 0, bearing the stop E, can pass through itsproper opening min the door-frame. When this is accomplished the doorreadily slips into its place. The hooks I) should slide and move withperfect ease in opening and closing the door, and for the purpose ofinsuring this ease sufficient clearance should be allowed in the openinga to permit the hooks I) to move freely therein. 7

It will be seen that with properly-fitted patterns, and with castingsmade therefrom with sufficient care, the parts constituting the hingesfor the door will fit together without requiring 0 any drilling or othermachine-work to adapt them, and that by my invention a saving will beeffected in time, labor, and material. It will also be readily seen thatby this construction I produce an effective hinge that is 5 entirelyconcealed from view when the-door is closed, and which leaves theexterior surface free from obstruction, and renders the operation ofpolishingthe stove much easier.

I am aware that it is not new to hinge a stove-door to lugs on theinside of a stove-front by means of pintles, the hinge being soconstructed as to be flush with the front of the stove when the door isclosed, but said hinge not being covered or shielded. This constructionis shown in the patent granted to A. Wemyss, March 28, 1876, No.175,312.

1 am also aware that it is not new to hinge a vertical door to astove-front by means of interlocking parts, the construction havingnothing to correspond to my device D, and being apparently incapable ofuse with a horizontal door. This construction is covered by patent of T.J. Ooulston, November 9, 1869, No. 96,551.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In combination with door B, arranged to overlap and shield the hingewhen closed, the curved hooks b I), attached to said door, one of whichisprovided with a stop, E, and the frame A, having openings act,'internal convex swells, O O, and guard-lugs D D, arranged to preventthe displacement of the horizontal door, substantially as set forth.
